Abstract:
Since the emergence of the lab-on-a-chip technology in 1979, a variety of microfluidic devices have been developed and utilized for chemical and biological applications. Among the microfluidic devices, the centrifugal microfluidic device or lab-on-a-disc (LOAD) has advanced remarkably due to simple operation by the rotation, total integration, and high-throughput capability. Moreover, the centrifugal microdevices do not need complex tubing and pumping systems, which render them ideal for point-of-care testing (POCT) system. Owing to these characteristics, the centrifugal microdevices have been extensively used for bio-diagnostics. In particular, molecular diagnostics, which are regarded as an essential method for definite determination of the targets related with diseases, have been widely applied on the LOAD. In this review paper, we focus on the molecular diagnostics on the LOAD. The steps for the molecular diagnostics such as cell lysis, genome purification, gene amplification, amplicon detection, and data analysis can be performed individually or totally on the LOAD. Future directions of the LOAD in the fields of bio-diagnostics is to realize POCT for U-healthcare monitoring. In this context, the latest LOAD strategies for molecular diagnostics are summarized in this review paper, which would provide an insight for future POCT platform.
